There are rubber marks all over the car. There are even some marks on the door handles and on top of the fenders. Back-to-back track days at Buttonwillow the Circuit and Classic tracks combined for a total of 12 sessions at about 17-18 minutes each resulting in lots of rubber accumulation time.
There were no issues with the AP Racing brake setup of course. I got around to measuring the actual pad thickness remaining and it’s about 10mm left on the front brakes, down from the original 18mm. I think this set of pads have six track days and a handful of fun drives in the canyons on them.
The rears are slightly thinner than the fronts. The pads should last another three track days.
Rain and sticky tires make the car a gravel collecting street sweeper. This is just some of the crap that came off the car.
More gravel and rubber.

Looking at stuff, I would say you need more roll stiffness, more negative camber, and less front caster.
I got shims from E-Motion to adjust the caster and camber. I just need to find time to adjust the alignment before my next track day. For more roll stiffness… I’ve been thinking about it for a while already. Commonly used is the Tractive setup, but Nitron released their new setup compatible with PASM/DSC. Looking at spring rates in the GT4 territory to keep that balance of streetability.
Can you please expand on the less front caster comment as it pertains to the 718 chassis? Is there a reason you suggest he might have too much and what would be a good target caster for a mixed use street/track 718?
It seems that it is common to end with 9 or 9.5 degrees caster on these cars.
Has anyone gotten these plugs yet? Seem like a decent upgrade.
Ruthenium HX is available in two designs to best maximize the performance of your engine.
DFE (double fine electrode) maximizes ignitability, while reducing emissions for low-heat engines. This NGK-patented design is recommended for non-turbo applications.
PSPE® (projected square platinum electrode) provides the best ignitability and service life for high-heat engines. This NGK-patented design is recommended for turbo and supercharged engines.

Interesting. I haven’t kept tabs on spark plug tech. The boring part of sticking with OEM plugs is that they are pre-gapped, ha.
